Laravel 日期时间格式无效：1366 字符串值不正确

I'm getting this error:

SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect string value: '\xBD Inch...' for column 'column-name' at row 1

我的数据库、表和列的格式为utf8mb4_unicode_ci，列名的类型为text和NULL.

这是列名的值

[column-name] => Some text before 11 ▒ and other text after, and after.

However I wait that laravel adds quotes to column's values, because the values are separated by commas (,). It should be as follow:

[column-name] => 'Some text before 11 ▒ and other text after, and after.'

请参阅下面的架构

    Schema::create('mws_orders', function (Blueprint $table) {
        $table->string('custom-id');
        $table->string('name');
        $table->string('description')->nullable();
        $table->string('comment')->nullable();
        $table->integer('count')->nullable();
        $table->text('column-name')->nullable();
        $table->timestamps();

        $table->primary('custom-id');
    });

我一直在谷歌上寻找，但还没有任何解决方案.

Anyone has an idea how to solve this issue?

I'm using Laravel 5.5 and MariaDB 10.2.11.
